Jesus appears to Norwegians as a giant spiral in the sky?

All over the web today, a giant spiral in the sky mystifies Norwegians. UFO? The return of Jesus? Most likely is a missile launch gone wrong. It appears the guidance system malfunctioned, causing the missile to spiral as it ascended. Once the missile cleared the atmosphere, ejecta from the missile (most likely its burn plume, possibly a leaking fuel tank) would no longer be slowed and absorbed by the atmosphere, spreading out into the (quite beautiful) spiral shape that has to be tens of km across. The spiral, back-lit by the below-the-horizon sun, would be visible until it dissipated, which apparently took a couple of minutes. The blue ray pointing at the spiral would be the remnant of its plume in the upper atmosphere.
